(54) METHODS FOR REJUVENATING AN IMAGING MEMBER OF AN INK-BASED DIGITAL PRINTING SYSTEM


(57) Disclosed herein are methods for an ink-based digital printing system, comprising providing an imaging member a reimageable surface layer disposed on a structural mounting layer, the reimageable surface layer comprising a fluorosilicone elastomer and an infrared-absorbing filler comprising carbon black, and a plurality of surface defects on the reimageable surface layer, wherein the surface defects comprises carbon black exposed through the fluorosilicone elastomer of the reimageable surface layer. The method also comprises applying a coating of rejuvenating oil comprising an amino-functional organopolysiloxane to the reimageable surface layer, whereby at least a portion of the plurality of surface defects are coated by the amino-functional organopolysiloxane, thereby rejuvenating the imaging member.
